Fiber MODEM: with 2-channel serial port fiber transmission, 1st interface RS422/485, 2nd interface RSS32 interface,FC dual core fibre 40 Km , DC power supply 9-55v, din rail installation.
This fiber optic MODEM provides 2-channel serial port fiber transmission, the first is to support RS422/485 interface, and the second is RSS32 interface. This product breaks through the contradiction between traditional serial interface communication distance and communication speed, and also solves electromagnetic interference. It greatly improves the reliability, security and confidentiality of data communication, and can be widely used in various industrial control, process control and traffic control occasions, especially suitable for banks, electric power and electromagnetic Departments and systems with special requirements for interference environments.
3. Features:
– Integrated circuits based on independent intellectual property rights；
– Provides up to 2 serial ports；
– Serial port 1 supports RS485/422 (two data interfaces are automatically identified), serial port 2 supports RS232 interface, 3-wire RS232 (TXD, RXD, GND)；
– RS485/422 channel can transmit asynchronous serial data adaptive from 0-512kbps baud rate, RS232 channel can transmit asynchronous serial data adaptive from 0-256kbps baud rate；
– It can be used as RS232/422/485 three business interfaces at the same time, which is convenient for on-site business opening;
– Serial port anti-radar to IEC61000-4-5 (8/20μS) differential mode: 6KV, impedance (2Ω); common mode: 6KV, impedance (2Ω) standard;
– DC9-55V or AC7-50V wide-range power supply, the power supply has automatic polarity detection function, no need to distinguish between positive and negative poles during installation；
-The power supply supports overload protection and anti-reverse connection protection; it meets the requirements of industrial four-level electromagnetic compatibility;
-Super lightning protection function: lightning protection, anti-induction high voltage, anti-surge, etc.; no fan for efficient heat dissipation, reducing repair time;
-Provide DIN 35mm rail mount, or wall mount；
